Specification forming part of Letters Patent No. 43,67 0, dated August 2, 1864.

To all whom, it may concern:

Be it4 known lthat l, G. F. J. GOLBURN, of Newark, inthe county ot' Essex and State of New J ersey, have invented a new and 'useful Improvement in vButt-Ilnges; and I do hereby declare that the following" is a full, clear, and exact description thereof, ywhich will enable others skilled in the art to make and use the saine, reference being had to the accompanying drawings, making a part ot' this specication, in which- Fignre'lris a view of' luy-invention in an open state; Fig. 2, a section of the same, taken in the lille .n a7, Fig. 1f; Fig. 3, a view of a modification of the same in an open state;

Fig. et, a section of Fig. 3, taken in the'line yy..

biinilar letters of reference idica-telik'e parts.

This invention has for its object the making ofa butt-hinge, 'providedwith pintle's, cnt ot' two pieces of metal only, in such a manner that the hinge may, with the same machinery used in its construction, be provided with'a stop toad-init of the hinge opening to any de.

sired angle. l

A, Figs. l and2, represents one part or leaf 'of the hinge, the main portion vof which' may be of the usual form, but at its inner edge it is notched vout ateach side, as shown at a a., so as toforln whatinay betrrmed a"1ip,77 b,and

two pintles, cc, which project at rightangles receive the pintles c c of the .leaf A. In this inode of construction it will be seen that thev lip I) serves as a stop and A.prevents the leaves A Bbeing turned beyond a pointin which the leaves will be in or about in the-same plane, (see Fig'. 2;) but by curving'or bending the lin` b at right angles withleaffA., as

shown in Fig. 4., the leaves whenopened will be prevented from assuming relatively with each other a greater angle than a right an'- gle; but this, it will be seen, may be varied as desired by bending the lip b to different angles relatively with the leat'A. In this latter modification I propose to have the leaf'A formed with two notches, a a, at each side of the lip b,- and the eyes o-r bearings ee, each notched' out, as shown at f f, Fig. 3, to form a double stop or bearing, insuring greater vstrength by preventing the contingency ofthe' bending ofthe lip b.- Thus it will be seen that I obtain a butt-hinge constructed out of two pieces only and provided with pintles and a stop, the latter being capable ot' being bent or adjusted to admit of the leaves -opening to any'desired-a'ngle. l l

1 do'not wish to confine myself strictly to the form or construction of the hinge shown f in the drawings, as hinges may, without alteration of -the principle herein set forth, be construeted or formed somewhat dilierently-as,

for instance, the stop may notl be confined to the center ot' the butt' or the pntle at the ends, but v.the stop may be at theendsand the. -pintle in the center should such 'moditieationbe required. v v

1 claim as Anew and desire to secure by Letters Patent- A bntt-hinge constructed out ot' two parts, and vI'irovid-ed `with pintles, and a stop, suhstantially as' herein shown-and described.
